Mars could contain liquid water despite the sub-zero temperatures that the planet currently registers, as demonstrated by a team of scientists from the Higher Council for Scientific Research (CSIC), in collaboration with NASA.
The researchers have reached this conclusion thanks to the development of an alternative model on the processes of evaporation and freezing of fluids with a geochemical composition deduced from data from the Martian missions Viking , Pathfinder , Opportunity and Spirit . The results of the study, published this week in the journal Nature , show that some of these fluids remain in a liquid state at temperatures of up to 50 degrees below zero.
The most interesting thing, according to Ricardo Amils, co-author of the study, is that "if there is liquid water, life is possible." The fluid that would exist on Mars, according to the working model used, would have a concentration of salts similar to that of seawater.
